An inner member (3) of the bearing assembly includes a hub axle (4) made of carbon steel and having a radially outwardly extending hub flange (22) formed on an outer peripheral surface of the hub axle (4) at a location adjacent the outboard end thereof, and an inner race member (5). The hub axle (4) has a radially inwardly depressed mount (4a) defined on the outer peripheral surface thereof at a location adjacent the inboard end thereof, and the inner race member (5) is fixedly mounted on the depressed mount (4a). A raceway (3b) is defined in an outer peripheral surface of the inner race member (5). The inner race member (5) has a radially inner end edge, delimited between an inner peripheral surface thereof and an annular inboard end face thereof, which edge is chamfered to represent a rounded inner end corner (5a), and is fixed on the depressed mount (4a) by means of an annular end stop (4c) that is formed by staking the inboard end of the hub axle so as to protrude radially outwardly. The hub axle (4) also includes a hardened layer (20) formed on a surface portion of the outer peripheral surface thereof at a region between a root (22a) of the hub flange (22) and the depressed mount (4a). An inboard end of the hardened layer extends to a position between the raceway (3b) and the rounded inner end corner (5a) of the inner race member (5).

    摘要： To provide an electrically powered brake system capable of performing a control of the braking force appropriate to a particular wheel rotational speed with high response and capable of being simplified in structure with no need to employ any hydraulic equipment and the related pipe lines, the electrically powered brake system includes an actuating unit 18 including a brake wheel 16 mounted on a vehicle wheel 1 and brake pieces 17 frictionally engageable with the brake wheel 16. A drive unit 19 is operable to translate a rotary output of an electric drive motor 20 into a rectilinear reciprocating motion by means of a ball screw mechanism 23, which rectilinear reciprocating motion is transmitted to the brake pieces 17 as a braking force. An operating unit 32 is operable to control the electric drive motor 20 according to manipulation of an operating member 31 such as, for example, a brake pedal. An anti-skid control device 35 is provided for regulating the braking force, exerted by the electric drive motor 20, in dependence on the number of revolutions of the vehicle wheel 1 during a braking effected by manipulation of the operating member 31. For a rotation detector 1 for detecting the number of revolutions of the vehicle wheel 1, the rotation detector 1 including a magnetic encoder 37 is employed.

    摘要： A wheel axle bearing unit for a vehicle is to be made lighter in weight, so as to prolong a life span thereof. A first grooved portion is formed by removing an excess in thickness in a region between dual raceways on an outer circumferential surface of a hub and an inner race which constitute the inner member of the wheel axle bearing unit, for enlarging a space inside the bearing, thereby increasing an amount of grease that can be retained in the region between the dual raceways. Also at a position corresponding to the first grooved portion, a second grooved portion is formed by removing an excess in thickness on an inner circumferential surface of an outer race, which constitutes an outer member.

    摘要： To reduce the weight of the wheel support bearing assembly without sacrificing the strength, the wheel support bearing assembly for rotatably supporting a vehicle wheel relative to a vehicle body structure includes a hub axle (2) formed with a radially outwardly extending hub flange (12). This hub flange (12) has an inner peripheral portion and a remaining wall portion other than the inner peripheral portion, and the remaining wall portion thereof is constituted by a plurality of radially outwardly extending ribs (13) each formed with a bolt insertion hole (14). The hub axle (2) also includes a brake pilot area (16) extending outwardly from an outboard face of the hub flange (12) for guiding an inner peripheral surface of the brake rotor (41). At least the root diameter (D1) of at least an inboard face of each rib (13) is chosen to be equal to or smaller than the outer diameter (D2) of the brake pilot area (16).

    摘要： To prevent vibrations and uneven wear of a brake resulting from runout of the brake rotor, a reliable wheel bearing assembly with a brake rotor is proposed which needs no troublesome runout adjustment at a car assembling factory. The assembly includes an outer member having two raceways on its inner circumferential surface, an inner member having raceways each provided opposite a respective one of the two raceways, and rolling elements arranged in two rows between the outer and inner members. One of the outer and inner members is provided with a wheel mounting flange, and the brake rotor is mounted to the wheel mounting flange. The runout variation of a side of the brake rotor is maintained within a standard value with a fixed-side member as a datum.

The wheel hub inner circumferential surface includes a serration (8). One or more inner rings (10) are press-fit onto a cylindrical portion (7) of the wheel hub (1, 14). An outer member (4) is arranged around the inner member (3, 16). The outer member (4) is formed with double row outer raceway surfaces (4a) on its inner circumferential surface opposite to inner raceway surfaces (10a). Double row rolling elements (5) are arranged between the inner and outer raceway surfaces (10a, 4a). A partition wall (9) is integrally formed on the wheel hub (1, 14), at its outboard side, to close a central bore of the wheel hub (1, 14).

    摘要： A vehicle wheel bearing apparatus has an outer member (10), an inner member (1) and double row rolling elements (6, 6) freely rollably arranged between the outer and inner raceway surfaces (10a, 10a; 2a, 3a), respectively, of the outer and inner members (10 and 1), via cages (7). An annular projection (12) is formed on the outer circumferential surface at an inboard side end of the cylindrical portion (2b) of the wheel hub (2). An annular recess (13) is formed on the inner circumferential surface at the inboard side end of the inner ring (3). The annular recess (13) corresponds to the annular projection (12) and has a difference in height slightly larger than that of the annular projection (12). The inner ring (3) is press fit onto the cylindrical portion (2b) of the wheel hub (2) with the recess (13) engaged by the projection (12).
